Important Rules of Tenses Below mentioned are some important rules and most common errors of Tenses in English Grammar
1) Do not get confused between use of Present continuous tense and Present perfect continuous Tense. To indicate an action which started in the past has gone on till the present
and is still continuing, We use the present perfect continuous tense. Using 'Present continuous tense in such sentences is incorrect. For example Incorrect It is raining for two days.
• Correct It
has been raining for two days.
2) Do not get confused between present perfect tense/the past perfect tense and simple past tense. Ina sentence,
With adverbs of past time like, 'last week, 'last Monday, 'yesterday, 'last night' etc, always use simple past tense. Using Present perfect tense is incorrect in these sentences. Present perfect tense is to denote an action that continued in present too. Past perfect tense is only used to talk about the earlier of two past actions. For example
• Incorrect I have seen him yesterday.
• Incorrect I had seen him yesterday.
•
Correct I saw him yesterday. Adjective Adjectives are the word which qualifies, describes or modifies nouns and pronouns by giving some
information about the size, shape, age, colour or material of some object. Adjectives are usually used before the nouns and pronouns. Adjectives cannot be used alone but they make the sentence meaningful by telling something special about the noun and pronoun.Some examples of Adjectives are Good, bitter, small, black, Fat, great etc. To know which adjective should be used where there are some rules which need to be understood properly.
For example : • I ate the dinner.
• I ate the delicious dinner. (Here Delicious word is adding more information to the word 'Dinner)
If in a sentence, there are more than one adjective to qualify/modify the same noun then we usually use a comma to separate those adjectives. No commas are used to separate the last adjective in the series from the noun it is qualifying. We can use any number of adjectives to qualify a noun. But we cannot put another word between an adjective and the noun it is qualifying.
